I have to admit, I really liked this game. At first I was confused and didn't understand why the arrow keys wouldn't work. But once it sunk in that he was lying to me... it became a bit easier.
4/5. Not a bad game, I agree that if there is more than one path you should be able to take either. And to whomever gives it a low rating because it's math... well, you're the one who decided to play it, no one made you do it.
